Restaurant Tip Calculator and Bill Splitter (Per Person, Evenly)
Tipping etiquette varies more than most travellers expect, and so does the base the tip is calculated on. In the United States the convention is a percentage of the pre-tax subtotal; in Canada many people tip on the total including GST/PST; in the UK a discretionary service charge is often already printed on the bill. This calculator lets you choose the base explicitly instead of assuming one.
| Tip % | Tip amount | Bill total | Per person |
|---|---|---|---|
| 10% | $11.11 | $131.11 | $32.78 |
| 15% | $16.67 | $136.67 | $34.17 |
| 18% | $20.00 | $140.00 | $35.00 |
| 20% | $22.22 | $142.22 | $35.56 |
| 22% | $24.44 | $144.44 | $36.11 |
| 25% | $27.78 | $147.78 | $36.94 |
Pre-tax versus post-tax tipping
On a $120 bill carrying 8% sales tax, tipping 18% pre-tax gives $20.00; tipping the same percentage on the full amount gives $21.60. It is a $1.60 difference on one meal, but roughly $150 a year for someone eating out twice a week — worth being deliberate about.
Splitting when the bill is uneven
Even splits are fastest but quietly overcharge the person who ordered a salad and tap water. A fair compromise used by many groups is to split shared items and tax evenly while assigning individual mains directly, then apply one group tip percentage across the whole total.
Rounding up without awkwardness
Rounding each share up to the nearest whole unit collects slightly more than the bill and avoids fumbling for coins. The tool shows the total collected next to the true total so you can see the surplus and either add it to the tip or hand it back.

People also ask
How much should I tip on a $100 bill?
At the common US standard of 18-20% on the pre-tax subtotal, that is $18-$20 for a $100 pre-tax meal. Exceptional service is usually acknowledged at 22-25%.
Should you tip on tax?
In the United States the customary base is the pre-tax subtotal, because sales tax is not part of the service value. Tipping on the total is generous but not expected.
How do you split a bill fairly when orders differ?
Assign individually ordered items to each person, split shared plates and tax proportionally, then apply one tip percentage across everyone's subtotal.

Quick answers about the Tip & Equal Bill Splitter
What exactly does the Tip & Equal Bill Splitter work out?
Tipping etiquette varies more than most travellers expect, and so does the base the tip is calculated on. You enter currency, bill amount, sales tax already on the bill and tip percentage (plus 3 more optional details) and the result panel updates straight away, so you can compare two or three versions of the same question in a few seconds.
What do I need before I start?
Only 7 fields: currency, bill amount, sales tax already on the bill, tip percentage, tip calculated on, number of people and rounding. Nothing else is needed and nothing is stored.
How is it calculated — pre-tax versus post-tax tipping?
On a $120 bill carrying 8% sales tax, tipping 18% pre-tax gives $20. The same maths runs inside this page, so hand-checking the result on paper gives you the identical figure.
Why do two calculators give me different answers for tip & Equal Bill Splitter?
Even splits are fastest but quietly overcharge the person who ordered a salad and tap water. Different sites pick different assumptions, so always check which method a calculator states before you trust the gap between two numbers.
What does the "International tipping norms" table on this page tell me?
It is the reference range this tool works against — 6 rows from "United States" (18-22%) up to "Japan" (None expected). Use it to sanity-check whether the number you just calculated sits where you expected it to.
Which currency should I pick?
The dropdown offers 5 choices — USD $, GBP £, EUR €, CAD C$ and AUD A$. Pick the one that matches your real situation rather than the one you would like to be true; currency usually moves the final figure more than any other single input, so it is worth running it twice with the option above and below your guess.
Does it work in both metric and imperial (or another currency)?
Yes. The "Currency" control converts every field and every result, so you never have to convert anything by hand before typing it in. Switch it after entering your numbers and the output re-renders instantly in the new system.
Do I have to press a button or reload the page to see the result?
No. Tip & Equal Bill Splitter runs completely inside your browser, so the moment you change a value the cards recalculate — there is no submit step, no page reload and no waiting for a server round trip. That also means it keeps working on a weak or intermittent mobile connection.
Is it free, and do you keep what I type?
It is free with no sign-up, no app install and no usage limit. Nothing you enter into Tip & Equal Bill Splitter leaves your device — the calculation is JavaScript running locally, so there is no upload of your figures to DrHint or anyone else.
Can I use it on a phone?
Yes — the layout stacks to a single column on small screens and the number fields open the numeric keypad on both Android and iOS. Many people bookmark this page or add it to their home screen and re-open it whenever the question comes up.
Anything to be careful about with the result?
At the common US standard of 18-20% on the pre-tax subtotal, that is $18-$20 for a $100 pre-tax meal. Treat the output as a well-grounded estimate for planning, not as a professional, legal or medical decision on its own.
